Ok so im having some trouble and cant seem to find the answers. I have been doing so work on my truck I replaced the trans about 4 months ago then the turbo ebpv blew and lost a lot of oil so I fixed all that and when I got it back on the road the overdrive light would come on steady not flashing and I would lose overdrive. I could push the button and is would go off. it did that for a day or two now the light comes on as soon as I turn on the truck and stays on. I pulled the steering column covers and checked the wiring. no issues there I check the pcm connection and cleaned and greased it. I also check the button with a multi meter and it works right. and I am getting 12v on the center pin and 2 on the right side pin on the connector on the column to the shifter. not sure what that means. I also checked on the connections on the transmission. any guidance would be nice thanks.
